Best tweeting by an art personality

For some unjustifiable reason the Chicago art scene has not taken on the habit of tweeting its guts out to the world unlike peeps in places like New York, Texas and even Puerto Rico. However, there are a few exceptions in Miguel Cortez, director of Antena Gallery (@lapsus5), and the Museum of Contemporary Art (@mcachicago). But it is the director of SideCar Gallery in Indiana, Michael Kaysen (@sidecarhammond), who reaches the far confines of the twitterverse by engaging in inflammatory discussions about art and politics with the likes of star critic Jerry Saltz (@jerrysaltz).
